Title:
BEAM DETERMINATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/168590
Kind Code:
A1
Abstract:
The embodiments of the present disclosure belong to the technical field of communications. Disclosed are a beam determination method and apparatus. The beam determination method is applied to a terminal device, and the method comprises: receiving beam indication information sent by a network device, wherein the beam indication information is used for indicating an associated reference signal identifier sequence within a specified time period, and associated reference signal identifiers in the associated reference signal identifier sequence are used for indicating a sending beam used by the network device, or the associated reference signal identifiers in the associated reference signal identifier sequence are used by a terminal device to determine its own sending beam. In this way, according to the beam indication information sent by the network device, the terminal device can determine the sending beam used by the network device within the specified time period, or determine its own sending beam within the specified time period, thereby improving the prediction and tracking efficiency of a beam.
